question_answer 1)

Calculate the mass percentage of benzene (C6H6) and carbon tetrachloride (CCl4) if 22 g of benzene is dissolved in 122 g of carbon tetrachloride.

Answer:

Mass of solution = Mass of benzene + Mass of carbon tetrachloride = 22 g + 122 g = 144 g Mass percentage of benzne   = 15.28%. Mass percentage of CCl4   = 84.72%.
